Caleb could also be included. His magical abilities could be useful in the fan fiction. He might also provide some intellectual support and different perspectives compared to Beau and Jester.
Fjord would be a good character to have. His skills with the sword and his own personal journey could intersect with Beau and Jester's story. Maybe he joins them on a particular quest and they have to work together to overcome obstacles.
Yasha would be a great addition. Her relationship with Beau and Jester could add an interesting dynamic. She could be the muscle when Beau and Jester get into trouble on their adventures.
One idea could be that Beau and Jester go on a journey to a hidden magical realm that's not known to their usual group. In this realm, they have to solve puzzles and face challenges that test their friendship in new ways.
Kakashi could also be included. He has a history with Obito, and his relationship with Itachi was also complex. His skills and his role as a mentor - like figure can bring a different dynamic to the story. For example, he could be the one who suspects something strange is going on between Itachi and Obito and tries to figure out their motives.
Patrick could be a great addition. His simple - mindedness could contrast with Sandy and Squidward's more complex personalities. He might accidentally cause chaos while Sandy and Squidward are trying to do something important, like a science experiment or a music recital.
Obviously Beavis and Butthead themselves are essential. Their unique personalities and idiocy drive most of the stories. Also, Mr. Van Driessen can be a great addition. His attempts to educate them often lead to hilarious situations.
An old - time medicine man could also be included. He could either be a healer who tries to cure Doc Holliday's illness or a trickster who causes more problems for him. This would introduce elements of Native American culture and mysticism to the fan fiction.
Spongebob is essential as the main character. Gary could be included, and perhaps in the fan fiction, Gary's meows are what lull Spongebob to sleep. Sandy could also be part of it, like she invents a new type of sleeping apparatus for Spongebob. And Mermaid Man and Barnacle Boy could make an appearance in Spongebob's dreams, where he teams up with them to fight off some sleep - stealing villains.
Sonic himself is a must - include character. After all, it's Sonic fan fiction. His speed, attitude, and sense of justice are central to any story. Tails is also a great addition. His intelligence and loyalty to Sonic can add depth to the story. And Knuckles, with his strength and his connection to the ancient ruins in the Sonic universe, can bring in an element of mystery. Dr. Eggman is another important character. His evil plans and his constant battles with Sonic are classic elements that can make the fan fiction exciting.
Toad could be a great addition. He's always been Princess Peach's loyal servant. He could try to rescue her in his own bumbling way when Bowser kidnaps her, adding some humor to the story.
There are many fan - created stories that focus on the positive aspects of Beau and Jester's relationship. You can search on popular fanfic platforms and filter for stories that are rated as 'General' or 'Teen' to find clean and enjoyable reads.
